The present invention pertains to a novel rope carrier for a paper making machlne,

wherein a. rope is moved along with the drier rollers. The rope is intended to keep. the sheet of paper in. motion even though it should break transversely, and ordinarily moves continuously with the drier rollers.

The present invention provides a. carrier which does not move constantly with the rollers but only when its service is required and therefore lying idle at, other times. Gonsequently, there is only a fraction. ofthe ordinary wear on the rope, the life. of whi'ch. is thereby considerably prolonged.

Furthermore, when the rope carrier is permanently geared to the drier rollers, the machine, must be shut down in order to, replace a rope. In the present. instance, the carrier is independent of the. rollers, and the. rope may therefore be changedwithout interrupting the operation of the machine...

The invention further. provides means for bringing the rope carrier into. driving rela tion with one of the rollers andreleasing it 25. therefrom at will.v

The invention is fully disclosed by way of" example in the following description andlin.

Figure 8 is a, similar section showing the.

Reference to these views-will now be made by use of like characters which will be employed to designate corresponding parts throughout;

In" Figure I is illustrated a portion of a paper makingmachine including a base 1 and a. frame side member 2. On the base and in the frame are journall'ed' drier rollers 3 of the usual type and in the customarystaggored relation.

Spokedj carrier rings l for the paper carrying rope are mounted adjacent one end of each of the, lower rollers 3-and are supported from the bearings 5 of" such rollers. The bearing is formed with a grooved race member 6surrounded' by the internally grooved" hub 7 of" the ring .4. Ball bearings 8 are interposed between theracemember and the hub as clearly shown in Figure 3;

The ringadjacent the upper roller is the driving member and is ofa two-part character including inner and outer rings 9and 10 respectively of angle cross section and concavedf at 11 in the angle thereof to provide a race for inter-posed ball bearings 12. The outer ring is formed in its outer periphery with a groove, 13 for receiving the rope as will presently appear. The face of this ring adjacent the end of the corresponding upper roller carries a. flat band 10" of friction material adapted'to engage said end, upon actuationof the, ringpresently to be described, in order to establish a driving connection between the roller and the ring.

The means for shifting the two-part ring includes bracketsv 14' secured to the frame 2' adjacent the upper, roller and grooved as at 15' to support an operating ring: 16 in a rotatable manner. This ring has two handles 17 by one or both. of which it may be turned. Iltwillfbe. seen by reference to Figures 9 and I0 that the operating ring 16 lies adjacent the. inner ring 9., The operating ringcarries a bracket 18 extending into the inner rin 9, andonthe. inner or under face of the brac ret is formed" an inclined cam face 19. The adjacent edge of the ring 9 is formed with a similar cooperating cam face 20, so that when the cam 1'9i's caused to pass the cam 20 by manual adjustment of the operating ring 16, in the direction of the downwardly pointing arrow in Figure 6, the ring 9 is moved towards the end of the adjacent roller, carrying with it the outer ring 10 and bringing the latter into frictional driving relation with the roller. The sliding support for the ring 9 is provided by grooves 21 formed in the brackets let parallel to the axes of the rollers 3 and entered by ribs 22 extending from ring.

The driving ring 10 is retract-ed from the adjacent roller by a pin 23 carried by the end of the bracket 18 and extending into a groove 24 formed in the inner circumference of the inner ring 9. This groove is inclined and parallel to the cam face 20, so that when the operating ring 16 is turned in the direction of the upwardly pointed arrow in Figure 5, the ring 9 is obviously pulled away from the adjacent roller. The outer ring 10 has a band 25 secured to its outer face, opposite the friction band 10, and overlapping the ring 9, whereby the ring 10 is withdrawn simultaneously with the ring 9.

Each ring f has a groove 26 in line with the groove 13 of the ring 10 in order to accommodate the paper rope 27. It will now be apparent that the carrier rings and rope are not in constant operation with the drier rollers, as in ordinary constructions, but are brought into operation only when wanted, by means of the operating ring 16, with the results that wear of the rings and rope are considerably reduced and the rope or other parts may be replaced or repaired without the necessity of shutting down the entire machine, as already indicated.

Although a specific embodiment of the invention has been illustrated and described, it will be understood that various alterations in the details of construction may be made without departing from the spirit of the invention as indicated by the appended claims.

Having thus fully disclosed my invention, whatI claim and desire to secure by Letters Patent is 1.
